Letters Patent No 92,976, dated Iuly 27, 1869.

IMPROVBMENT IN VELOCIPEDES.

The Schedule refexed to in these Letters Patent and making part of the same.

To ull whom it may concem:

Be it known that I, Jon:u LAUER, of Chicago, in the oounty of Cook, and State of Illinois, have in: vented an Improved Velocipede; and I (lo hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanyiug drawings, and letters marked thereon, making a part of this specificatior, in which Figure 1 is a perspective representation of my invention.

The nature of the present invcntion consists in combining, with a velocipede, auxiliary wheels for keeping it; from upsettng, connecting-rods,levers, and a disk for operating them, and a spring-seat,'ttached toa spring-standard, as the whole is hereinafter fully shown.

A represents the forward, and B, the rear wheel of an ordinary velocipede, said wheels being connected by a reach, E, and guide-standard, F, in the usual 1nanner.

D D, curved arms, which extend out from the axle m of the wheel B, and support an auxiliary wheel, G, on each side of said wheel B.

These wheels are arranged to be raised and lowered by means of the following devices:

A lever, L, is attached to the arde m, and its outer end is jointed to a connedting-rod, M, which extends forward, and fastens to a'con'necting-rod, n,-attached to a shaft, T.

This shift has a bearing in' a disk or plate, O, and to its opposite end is fastened a lever, P, which is used by the operator to fix the position of the wheels C.

A spring-catch, Q S, attached to said lever, looks into notches R in the disk, and thus liolds the lever in place, and also the wheels C.

with the wheels C bearing upon the track. hen, when a suflicient motion is attained, bring the lever P one.

notch forward on the disk lt O. This will raise the wheels C about four inches above the track, as shown by d0tted lines N, and enable the operatonto run on the wheels A B, and to pass over rutty and uneven ground without being readily upset.

By moving the lever P one uotch further, the wheels 0 Will be so raised up as to be canied'entirely above the ground.

Having thus described my invention,

What I claim, and desire to secure by Letters Pat- V ent of the United States, is

The combination of the wheelsA B, reach E, connecting-rod M, lever P, disk O, standard F F, springstandards K, spring-seat plate J, and seat I, all combined, arranged, and operating as herein shown and described.
